There's more to the story:
"Fail Safe and Dr. Strangelove were both produced in the period after the Cuban Missile Crisis, when people became more sensitive to the threat of nuclear war. Fail Safe so closely resembled Peter George's novel Red Alert, on which Dr. Strangelove was based, that Dr. Strangelove screenwriter/director Stanley Kubrick and George filed a copyright infringement lawsuit."
